Abstract (en)

A Propagation Test instruction, a Decay Test instruction and a Cycle Test instruction provide testing of DC and AC interconnect circuits between circuits including JTAG boundary scan cells. A few additions to the Test Access Port circuitry and the boundary scan cells are required to implement the additional instructions. The instructions are extensions of the conventional JTAG operating structure. <IMAGE>
